Be it known that I, .HInAM TYLER, of Gaines, in the county of Orleans,'and State of New York,h-ave invented anew and improvedlPui-np; `and I do Vhereby declare that the following is a full, clear, and exact.'

description thereof, which will enable'others skilled inthe art to make and use thesame, reference being had to the accompanying drawings, forming part of this specification in which- I Figure 1 is a vertical central section of my invention.

Figure 2 a detached and enlarged central section of ayalve pertaining to the same. This invention relates to a new and improved double-acting pump, and it consists in a novel arrangemen of valves and water passages, and in .an improved construction of the valves, as hereinafter fully 'shown and described, whereby the pump is rendered very eiiicient inits operation, the parts not liable to getout of repair or--be'com'e deranged by use, andthe pump capable'of-b'eing used either submerged or above the level of4 the wete-nto be raised or forced up. i A

I ,A represents the cylinder of the pump"y B, the piston fitted therein, and C the piston-rod. These parts may beef usual construction, and therefore Ado not require a minute description. D D represent two tubes,

.which ure parallel with the cylinderf, D being. the suction, and D the. force tube. In tig. 1, the pump is represented constructed with a view of being submerged, the watei` passing into tube D -through holes at in its sido, -the bottom or lower end being closed. The tubel D has a pipe E attached,w hich extends up to the top of the well, The piston B is operated'by a brake or lever,'F. lfhe'suctiontubejl) communicates with thecy-linder Ar by means of two hqrizontaltubes, Gr G, one at thel upper and the other at Athe lower part of the cylinder and tube', and'within these tubes G G, valves H H are placed, opening inward, or inal direction towards cylinder A.' The tube D communicatesrwiththe cylinder 'A by means of two similar tubes I I', providedhwith valves -K K", opening outward, or towards the tube D', as shown, clearly in iig. 1.

From .the above description it will be seen that when the vpiston B is rising, the valve H in .the -tnb'e G opens, wliilethe .valve K in the tube Icloses, and the water is drawn into the lower part of cylinder A, underneath the piston, as indicated by the arrows 1, w-hilcthe water iii-the cylinder A, above the'pistonB, is forcedthrough valve K in tube into the upper part of tube D and up through the pipe E, the valve- H, .in ltube G, being closed. When the 'piston B'descends, the valve in tube Gr closes, and the water below the piston is forced through valve Kin the tube I -into the tube D and up'through the pipe E, while the valve K in the tube I closes, and the valve H in tube G opens, to admit Vwater into the cylinder above the piston. Thus'- it'wil-l be seen that Ithe pump is double acting, `or throws a continuous stream; and it will further be seen that the pump may beused above the surface of theV water to lbe yraised. by having a. suction pipe attached to the lower end ofthe tube D. The construction of the valvescon'stitutesan important featureof. the invention, as the valves of a pump `are -very liable Vtofget out ofl repair, andA frequently-.cause a. great deal of trouble and inconvenience. L represents .the valvvestem, which is fitted i'n suitable guides b b, and is allowed to slide freely therein, the guides being attached to the annular pieceof metal M, on which the'seat c of the valveis formed,

as shown clearly in iig. 2. N is the valve, through 'the centre of the inner sidelof which thelro'd or stemlipasses, and is secured by a nut, d, the valve being allowed to work or play on the rod or stem in the same way as if it were connected by a ball and socket-joint, so that it may conform or adjust itself to the seat c. 'This kind of valve, as ordinarily construct ed,'is very liable-to workimperfectly, in consequence of the great diiiiculty inadjusting the valve N to the rod or stem' L in a plane at vright/'angles therewith, and parallel with the seat c, and as thevalve and its 'stem lare allowed to turn freely, the former will not, except in very rare instances, always t snugly to its seatg-hut, by having the valve ttedon its-rod or stem, as shown, so'that itmay work or play on the rod or stem, and'adjust itself to its seat, the valve will always work perfectly. i

Having thus described my invention, I-claim as new, and desire to secure by Letters Patent-- The valve N, attached to-the end of the sliding-rod Lby means of the nut d, so as to permit the said valve to playon the rod, as'herein described.; piece M, and guides b @when all are constructed and arranged as herein `set forth.- v v The above specification of my invention signed by me this 15th dayof August, 1866.
